Yes, that's exactly where the discussion started, somebody asked if
there was a single-chip hex 7-seg decoder, the 9368 (and other 93xx)
were pointed out.
In combinational logic I'm looking at turning 34
segments OFF instead
of
turning 78 segments ON. No discrete parts. I'm a purist.
I'm still looking at permutations to see if I can eliminate a couple
more AND gates and get it down to 9 packages from 10 (for the SSI
solution).
